[PATCH] arm64: dts: rockchip: orangepi-5: fix PCIe 3.3V regulator voltage

[Mykola Kvach]

The vcc3v3_pcie20 fixed regulator powers the PCIe device-side 3.3V
rail for pcie2x1l2 via vpcie3v3-supply. The DTS mistakenly set its
regulator-min/max-microvolt to 1800000. Correct both to 3300000
to match the rail name, the PCIe/M.2 power requirement, and the
actual hardware wiring on Orange Pi 5.

I guess a "Fixes" tag is in order here:

The vcc3v3_pcie20 fixed regulator powers the PCIe device-side 3.3V rail
for pcie2x1l2 via vpcie3v3-supply. The DTS mistakenly set its
regulator-min/max-microvolt to 1800000 (1.8 V). Correct both to 3300000
(3.3 V) to match the rail name, the PCIe/M.2 power requirement, and the
actual hardware wiring on Orange Pi 5.

Applied, thanks!

Please start new threads when sending version x+1 and don't append
that new patch to the old thread (less confusing for tooling like b4).
